I guess I'm just an oddball. Spending 5 minutes to hang my clothes seems like a tiny price to pay to save a ton of energy the way the rest of most of the world does. But I guess the HN crowd are mostly gated community techies who can't be bothered to walk three blocks to a supermarket, either. So I'm yelling at clouds here

I moved to the UK, and also got a dryer at that point.

The weather in the UK can be very humid, and if you don't have much of a garden, it can be impossible to dry your clothes at times. We've had times where our living room was full of clothes for more than a few days, and it wouldn't matter because it wouldn't really dry anyway.

So we've invested in dehumidifiers and a dryer, and it made our life a lot more comfortable.

Like others said, weather and conditions. During summers here clothes dry in an hour during the day, and they're half ironed to boot. In the winters however... I still remember bringing my jeans back inside as a slab of ice, and having foggy windows due to drying indoors.

The UK has huge problems with mould growth caused by damp. Drying clothes indoors is one of the causes. Energy is expensive so people don't heat their homes properly. Those two things combined cause mould which leads to severe health problems.
